| ABSTRACT The low boiling point compositions in inks for ink-jet printing were analysed and a direct dye for inks was synthesised in this paper.On the basis of the study of the relations between the prescriptons of inks and their functions, the optimal inks for ink-jet printing was prepared.Their parameters of physical chemistry were determined and their effect of recording were compared with that of inks in original ink box. In addition ,the reactive dyes for textile dying were analysed in this paper.The structral correction of dye was verified through synthesis ,paper chromatography and absorption spectroscopy.At the same time,a series of liquid acid dyes which can be used to manufacture inks for ink-jet printing were prepared.They have good storage stability and their quality index can meet demands of production. |
